WILLIAM E. FARRELL, OF HENSLEY, ARKANSAS, ASSIGNOR TO CATHERINE IVI. FARRELL, OF LITTLE ROCK, ARKANSAS.

DRY-KILN.

To all whom it may concern.

Be it known that I, WILLIAM E. FARRELL, a citizen of the United States, residing at Hensley, in the county of Saline and State of Arkansas, have invented new and useful Improvements in Dry-Kilns, of which the following is a specification.

This invention relates to dry kilns and the object of the invention is the provision of means whereby the waste products of combustion, smoke and the like, or heated air from the smoke stack of the engine used to produce the products, may be utilized to subsequently dry the products. The invention recited in my caveat, filed November 12, 1909, illustrates a saw mill engine, the heat and waste products of combustion from the smoke stack of which are utilized in a dry kiln to dry lumber cut by the engine. It is obvious that, while a similar construction is shown herein, the device may be adopted very readily in connection with brick kilns and the engines of the brick compressors, or in any other place where an engine is used to form or to assist in forming articles which afterward have to be dried.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which Figure 1 is a side elevation. Fig. 2 is a top plan view with the top broken away.

Referring more particularly to the draw ing, 1 represents an engine boiler from which the steam is taken to suitable mechanism, not shown, for cutting up lumber, compressing brick, or performing any other function desired. The boiler is provided with the usual smoke stack 2 and connected thereto and to a blower 3 is an outlet or discharge pipe 4:. This blower is here shown as driven by a belt 5 from a power shaft 6 which may be connected to the engine driven by the steam from the boiler or may be an auxiliary prime mover, as is found desirable. Moving away from the blower 3 is a Specification of Letters Patent.

Serial No. 627,044.

discharge pipe 7 which passes into a kiln S and is connected to a suitable radiating pipe 9 which extends alongside of the kiln and corresponds with a similar radiating pipe 10 arranged upon the opposite side of the kiln and having a discharge pipe 11 connected thereto. The pipes 9 and 10 are connected at a plurality of points by radiating pipes 12 which extend across the kiln and are arranged beneath the tracks 13 therein. The pipe 7 is provided with suitable expansions 14. and the pipes 9 and 10 and also the pipes 12 may be supplied with such joints if found to be necessary.

Extending from a point adjacent the engine or the saw carriage is a track 15 which communicates with the track 13 and upon which is adapted to travel a transfer car 16 upon which the lumber is mounted. After the transfer car has been properly loaded it is run along the tracks 15 and then is moved from its truck laterally into the kiln and the doors then closed and the truck moved back along the track to receive another transfer car, and the transfer car which is in the kiln may be moved out of the kiln with the dried lumber thereon.

Having thus described the invention, what I claim as new is A drying kiln comprising a closed compartment, a plurality of spaced-apart longitudinally extending elevated tracks disposed within said compartment, oppositely arranged pipes extending longitudinally along two sides of said compartment, and laterally of said tracks, a spaced apart series of pipes connecting said firstnamed pipes transversely and passing beneath said tracks, a feed pipe connected to one of said longitudinally extending pipes, and an outlet pipe opening out of said other longitudi nally extending pipe.

in testimony whereof I affix my signature in presence of two witnesses.

YVILLIAM E. FARRELL.
